Rossii?

I swapped a few accents with Xavier back in the Spring and one of them was this chap. I can’t seem to actually find out more about it. It was labelled Mukdenia Rossi. I was expecting the Rossi to refer to red flowers at some point, but as you can see, there appears to be a red tinge to the leaves starting as we come into Autumn. I have since read that it’s now to be called Aceriphyllum rossii. Anybody know any more about it as an accent?
